Jquery migrate some code form .live() to .on()

Question

How to migrated this code?

 $("#contact-form").find('textarea,input').jqBootstrapValidation({
            preventSubmit: true,
            submitError: function ($form, event, errors) {
               
            },
            submitSuccess: function ($form, event) {
                event.preventDefault(); 
 
                if (validate()) {
                    sendFormData();
                }
                else {
                    messageSendError("Warning! Please validate captcha before send new message.");
                }

                return false;

            },
            filter: function () {
                return $(this).is(":visible");
            },
        });

I try this one. No luck. What am I doing wrong?

 $(document).on('find', '#contact-form', 'textarea,input', function () {

            $(this).jqBootstrapValidation({
                preventSubmit: true,
                submitError: function ($form, event, errors) {

                },
                submitSuccess: function ($form, event) {
                    event.preventDefault();    
                    if (validate()) {
                        // sendFormData();
                    }
                    else {
                        // messageSendError("Warning!.");
                    }

                    return false;

                },
                filter: function () {
                    return $(this).is(":visible");
                },
            });

        });

The 3th parametar which I pass is 'textarea,input'? Is this a wrong? How to converted? The live method was easy. This .on() is difficult is difficult and more complicated .
